hi LucasCorso,which three different offsets do you meaning,is like the https://wiki.mobileread.com/wiki/MOBI#MOBI_Header
and your program modify them all?
and I also can't find 20 0xFFs or so... in the header
I just find 16 0xFFs after "mobi"
here is my screenshot
if input 20 0xFFs in the find filed, here is the first found
